Evading anti-virus using the GPU
This article is very interesting.
From the paper's abstract:
"Malware writers constantly seek new methods to obfuscate
their code so as to evade detection by virus scanners.
Two code-armoring techniques that pose significant challenges
to existing malicious-code detection and analysis
systems are unpacking and run-time polymorphism. In this
paper, we demonstrate how malware can increase its robustness
against detection by taking advantage of the ubiquitous
Graphics Processing Unit. We have designed and
implemented unpacking and run-time polymorphism for a
GPU, and tested them using existing graphics hardware. We
also discuss how upcoming GPU features can be utilized to
build even more robust, evasive, and functional malware."
